Hi and welcome! You've probably picked a good time to buy. In this economy there are deals to be had.
The spam is a relatively recent issue, just the last couple of weeks. This site doesn't get a huge amount of traffic so it doesn't take much to dominate the postings. Not sure about the moderators, certainly no has monitored in the last couple of weeks or Girard82 would have been banned and the posts deleted.
Good luck with your search!
